A mechanic working on a heavy truck’s axle assembly knows exactly why the 325mm size matters here—you’re reaching deep into a cramped wheel hub to pop out a stubborn external circlip, and the straight tip won’t slip off the groove on oily steel. Usually the 200mm handles common bearing caps in automotive differentials, but for large machinery, you’ll need that extra length for around suspension arms without the tips bending. It’s pretty straightforward: pick the size matching your clip diameter, and the drop-forged construction keeps the jaws from spreading apart under repeated shocks.
tip diameter on these runs form 1.5mm up to 3.5mm across five or so size variants, with 45# carbon steel or CRV (depends on the batch—we often have both) getting a full black oxide finish after hardening and tempering. Hardness typically lands around HRC 48-52, which means the tips won’t deform when you’re prying a 3mm clip from a stubborn shaft shoulder, but they’re not brittle enough to snap if you tap them with a hammer. Full black surfce isn’t just cosmetic—it resists light rust in humid shop air, though don’t leave them soaked in coolant overnight (that’s true for any coated pliers). Also, teh straight tip profile limits reach into blind holes—that’s just geometry, not a flaw.
For indutrial maintenance, we’ve seen these used on conveyor roller bearings and hydraulic cylinder retainers, where the uncoated handle gives you a solid grip even when your gloves are soaked in hydraulic fluid.: they’re not suited for internal circlips (different jaw spacing and angle), so a buyer stuffing up an order for those will be sending it back. Most shops just grab the 150mm or 175mm for 80% of engine and transmission work, while the 325mm collects dust until a combine harvester comes in for repairs.
We ship these in polybags with a card tag, MOQ is 50 pairs for custom labeling, but stock sizes go single piece. Lead time is typically 15 days or so—confirm before placing a rush order.
We typically require a minimum order of 500 pieces per size, but we can negotiate if you're looking to mix sizes in one shipment.
Yes, we can supply mill test reports for the steel batch upon request. Just let us know which material you prefer when ordering.
Standard lead time is 15-20 days after order confirmation, depending on current production load. We can expedite for larger volumes.
Yes, the tips are hardened and tempered for wear resistance. They cover a diameter range from 1.5mm to 3.5mm, suitable for most external circlips.
They come in polybags or blister packs, then in standard export cartons. Handle color customization is possible with a minimum of 2000 pieces per color.
